You have an impressive background, but so do tens of thousands of other applicants to these schools. That’s why it’s extremely difficult to “chance” you. If you want a number, your odds are likely in the low single digits (around 1–3%). Sorry, that’s just the reality.
Also, none of the schools on your list offer merit scholarships; they only provide need-based financial aid. Use the Net Price Calculators on their websites to estimate what you might receive. (Note: they’re not fully accurate for international students, but they’ll give you a good idea.)
If you’re serious about finding affordable options in the US where you’re more likely to be admitted, you’ll need to look much further down the prestige ladder. Don’t dismiss tsbna’s suggestions too quickly.
